Black Hole

**A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. There are many black hole in space..** *Q:Which is the nearest black hole to Earth?* The closest black hole to Earth that we know of is named V616 Monocerotis. It is also known as A0620-00. This black hole is 6.6 times more massive than our Sun. *Q:What can survive in a black hole?* Nothing can survive a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home. Aside from this, your body would be stretched and destroyed by the warping of space and the amount of radiation surrounding the event horizon. *Q:Where are black holes?* Observational evidence indicates that nearly all large galaxies contain a supermassive black hole, located at the galaxy's center. *Q:Can we create a black hole?* A black hole can have any mass equal to or above about 2.2×10−8 kg or 22 micrograms (the Planck mass). To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light. *Q:Can you see inside a black hole?* **Black holes** have gravitational fields so strong that even light cannot escape, so they are defined by the shell of a **black**, featureless sphere called an event horizon. But the **holes can** nevertheless **be seen**. As they consume matter that strays too close, they squeeze it into a superheated disk of glowing gas
